  abstract = {{B}ackground: {A}nopheles funestus is one of the major malaria vectors in tropical {A}frica. {B}ecause of several cycles of drought events that occurred during the 1970s, this species had disappeared from many parts of sahelian {A}frica, including the {S}enegal {R}iver basin. {H}owever, this zone has been re-colonized during the last decade by {A}n. funestus, following the implementation of two dams on the {S}enegal {R}iver. {P}revious studies in that area revealed heterogeneity at the biological and chromosomal level among these recent populations. {M}ethods: {H}ere, we studied the genetic structure of the newly established mosquito populations using eleven microsatellite markers in four villages of the {S}enegal {R}iver basin and compared it to another {A}n. funestus population located in the sudanian domain. {R}esults: {O}ur results presume {H}ardy {W}einberg equilibrium in each {A}n. funestus population, suggesting a situation of panmixia. {M}oreover, no signal from bottleneck or population expansion was detected across populations. {T}he tests of genetic differentiation between sites revealed a slight but significant division into three distinct genetic entities. {G}enetic distance between populations from the {S}enegal {R}iver basin and sudanian domain was correlated to geographical distance. {I}n contrast, sub-division into the {S}enegal {R}iver basin was not correlated to geographic distance, rather to local adaptation. {C}onclusions: {T}he high genetic diversity among populations from {S}enegal {R}iver basin coupled with no evidence of bottleneck and with a gene flow with southern population suggests that the re-colonization was likely carried out by a massive and repeated stepping-stone dispersion starting from the neighboring areas where {A}n. funestus endured.},
